Abstract

An apparatus for producing a corrected reconstructed image from magnetic resonance imaging data acquired by a magnetic resonance imaging scanner (10) includes a reconstruction processor (44) that reconstructs a corrected reconstructed image from acquired magnetic resonance imaging data. A parameters calculation processor (52) determines at least one characteristic of the imaging subject. A correction pattern adjustment processor (54) selects a correction pattern from a family of stored correction patterns based on the at least one characteristic. An image correction processor (56) corrects the uncorrected reconstructed image using the selected correction pattern to produce the corrected reconstructed image.
